Lambda phage will enter bacteria more easily than plasmids, making it a useful vector that can either destroy or become part of the host's DNA. [31] Lambda phage can also be manipulated and used as an anti-cancer vaccine that targets human aspartyl (asparaginyl) β-hydroxylase (ASPH, HAAH), which has been shown to be beneficial in cases of ...
A cosmid is a type of hybrid plasmid that contains a Lambda phage cos sequence. [1] Often used as cloning vectors in genetic engineering, cosmids can be used to build genomic libraries. They were first described by Collins and Hohn in 1978. [2] Cosmids can contain 37 to 52 (normally 45) kb of DNA, limits based on the normal bacteriophage ...
In molecular biology, the Cro repressor family is a family of repressor proteins in bacteriophage lambda that includes the Cro repressor.. Bacteriophage lambda encodes two repressors: the Cro repressor that acts to turn off early gene transcription during the lytic cycle, and the lambda or cI repressor required to maintain lysogenic growth.
Lambdavirus (synonyms Lambda-like viruses, Lambda-like phages, Lambda phage group, Lambda phage) is a genus of viruses in the order Caudovirales, in the family Siphoviridae. Bacteria serve as natural hosts, with transmission achieved through passive diffusion. There are five species in this genus.
When the Integration Host Factor was first discovered, it was only known for the site-specific recombination of bacteriophage. [4] This is all we knew for a while but through another article, we were able to find that with further research, IHF plays a key role in the scope of physiological processes of E. Coli, including site-specific recombination activities, phage packaging and partitioning ...
[4] cII acts as a transcriptional activator of three promoters on the phage genome: pI, pRE, and pAQ. [3] cII is an unstable protein with a half-life as short as 1.5 mins at 37˚C, [5] enabling rapid fluctuations in its concentration. First isolated in 1982, [6] cII's function in lambda's regulatory network has been extensively studied.
Phage display of antibody libraries has become a powerful method for both studying the immune response as well as a method to rapidly select and evolve human antibodies for therapy. Antibody phage display was later used by Carlos F. Barbas at The Scripps Research Institute to create synthetic human antibody libraries, a principle first patented ...
The toxin is effective against small blood vessels, such as found in the digestive tract, the kidney, and lungs, but not against large vessels such as the arteries or major veins. A specific target for the toxin appears to be the vascular endothelium of the glomerulus. This is the filtering structure that is a key to the function of the kidney.
